Question

I need help in Kahn academy

Answer 1

First, convert the mixed fractions into improper fractions:

3$\frac{1}{8}$ = $\frac{8(3) + 1}{8}$ = $\frac{25}{8}$

1$\frac{2}{3}$ = $\frac{3(1) + 2}{3}$ = $\frac{5}{3}$

Next, divide a fraction by multiplying by the reciprocal:

$\frac{25}{8}$ ÷ $\frac{5}{3}$ = $\frac{25}{8}$ x $\frac{3}{5}$ = $\frac{25(3)}{8(5)}$

Lastly, simplify the fraction:

$\frac{5(3)}{8}$ = $\frac{15}{8}$

Answer: $\frac{15}{8}$ = 1$\frac{7}{8}$
